Boxing fans can watch the Kell Brook vs. Errol Spence Jr. match live online and see if the British boxer can maintain his belt against the undefeated and quickly rising Spence.

The pair will face off Saturday in a bout from Sheffield, England. The main event is expected to start around 6 p.m. ET (10 p.m. GMT), and will be broadcast on television both in the United States and U.K. (with links to the streaming video available below).

Those who watch the Kell Brook vs. Errol Spence Jr. fight live online will likely see a strong performance from Brook, the IBF welterweight belt holder. Brook noted that it took him “a whole career to claim this belt against Shawn Porter,” and isn’t too keen on giving it up.

“I’m too stubborn just to give it up, and if Spence wants this belt, he’s going to have to rip it from me in front of 27 thousand fans in my home town,” Brook told the Telegraph.

“I had a great camp making the weight, and training for this and I will be drawing off that support to get the most out of myself. There’s going to be drama in this fight, and I am going to the wire — and the trenches — if I have to, to keep it.”

Spence didn’t have as much to say but was confident of his chances against the hometown slugger.

“But I’m going to prove myself Saturday night. I have the skills and ability to beat Kell Brook,” he said.

Spence has been letting his fists do the talking, with an impressive 21-0 record including 18 knockouts. He also scored a TKO against Chris Algieri, who had beaten both Manny Pacquiao and Amir Khan.

One of Brook’s most impressive bouts actually came in a loss last September to Gennady Golovkin, giving the undefeated champion his most difficult time yet. Brook was one of the first top-rank opponents to step up against GGG, who is now in a string of high-profile matches. Many credit Brook for getting that trend started, even though he lost the match last year.

Many experts are seeing the Brook vs. Spence fight as something of a toss-up, with either fighter likely to come out on top.

“I think it is a 50/50 fight. I think the person with the better game plan is going to win. It is a lot of pressure to go into someone’s backyard like that.”

Adam Booth predicted that whichever fighter can jump out to a strong start will likely take advantage. This is especially true if Brook allows his opponent to set the tone for the fight, Booth told Sky Sports.

“The first three or four rounds will decide who comes out as the winner,” Booth said.

“If Kell allows someone as polished as Spence to get into his groove and read his timing it is going to get harder and harder. It goes for both of them, it is easy to say, but whoever imposes themselves early on, they will do it.”
